HUGO BURGKAS, OF LEIPSIO, SAXONY, GERMANY.

MECHANICAL- MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 343,795, dated June 15, 1886.

Application filed May 527, 1885.

To all whom it may concern.-

Be it known that I, HUGO BUROKAS, residing at Leipsic, Germany, have invented new and useful Improvements in Musical Instruments, of which the following specification is a full, clear, and exact description.

This invention relates to a novel construction of reed-instruments; and it consists in the elements ofiniprovement hereinafter more fully pointed out.

In the accompanying drawings, Figure l is a section of a musical instrument embodying my invention. Fig. 2 is a cross-section at line a: m, Fig. I. Fig. 3 is a section of a musical instrument having only a single note-sheet. Fig. 4 is a cross-section at line y 3 Fig. 3. Fig. 5 is a side view ofa note-sheet, and Fig. 5 a plan of part of the same. Fig. 6 is a top view of the instrument with the note-sheet and its supporting-ring removed. Fig. 7 showsa plan of arrangement of the reed-valves in the upper box, and Fig. 8 the pins and rods for operating the same. Fig. 9 shows plan of arrangement of the reed-valves in the lower musical box. Fig. 10 shows a variation of arrangement of pins and levers for operating these valves. Fig. 11 shows plan of a different arrangement of the reed-valves. Figs. 12 and 13 show the arrangements of the rods and levers for operating the reed-valves, Fig. 12 showing the valves open, and Fig. 13 showing the same closed.

Similar letters representsiniilar parts in all the figures.

A represents the general casing,in which a ring, R, is arranged, supported in-its circumference by rollers r, and provided with suitable teeth on its periphery, into which the worm S works to give an axial'motion to said ring R. The worm S is placed upon a shaft, W, supported in the casing A, and operated by a handle, IV.

Upon the ring R two conical-shaped perforated music-sheets, N N, are placed, separated from each other by a ring, it, placed at their circumferences between the same.

In a line with the rods a,which operate the reed-va1ves, a bar, F, is arranged between the music-sheets N N, one end of which is attached to a bracket,G, fixed to the inner reedbox, 0. Below the lower music-sheet, N, the reed-box O is arranged, and above the upper Serial No. 166,827.

(No model.)

music-sheet, N, a reed-box, B, is placed, attached by means of hinges to the casing A. By this arrangement of two music-sheets with two reed-boxes the capacity of the instrument is considerably increased without increasing materially the general dimensions of the instrument.

In the casing A the bellows L are situated, operated through the rod to from the shaft \V. The air or wind produced by said bellows passes through the channels or tubes M M (which latter support likewise the reed-box G) into the air-chamber of the reed-box G, and through the passage-way or tube E into the airchamber of the reed-box B. This chamber is connected with the tube E by means of a flexible tube. D, which allows the turning of this musical box 13 onits hinges.

I11 case only a single music-sheet is used, as shown in Fig. 3, a bar, F, is hinged to the casing A in a line with the pins a, bearing upon the music-sheet N. p

The reed-boxes O and B contain the usual 166d-VfllV6,U,WhlCll may be arranged as shown in Figs. 7, 9, and 11, or in any other suitable cluster which may be found most convenient. These reed-valves are operated from rods a, connected either directly to the valves, as shown in Fig. 8, or said rods a are connected to spring-levers b, one end of which is attached by a screw,e,to the reed-plate r ,and the other end is attached to the reed-valve, as shown in Figs. 12 and 13. The rods a are arranged either side by side, as shown in Fig. 9, or in a zigzag line, as shown in Figs. 10 and 11, at right angles with the surface of the music-sheet, and are guided by tubes h, attached to the ends of the reedboxes G and B. The upper ends of these rods a are flattened, and the side,a,next the way in which the music-sheet moves is made wedge-shaped, so that the end of the perforations,coming in contact with these wedge-shaped sides a,willforce the rod (1 out of the perforations toward the inside of the reed-box, and thus close the reedvalves. The springlevers b are actuated by springs c,acting so as to force the same open, while the rods a, connected to the top ofsaid levers I), keep the same closed, except when they enter one of the perforations in the music sheet, whereby the reed valves can open through the action of the spring 0.

5 being regulated.

To prevent any unevenness of the musics'heet to effect the reed-valves when closed,

the rods a are connected to the levers b by the introduction of an elastic piece, d, capable of By this arrangement of opcrating the reed-valves by a direct-moving rod, a, acting at right angles to the surface of the music-sheet, either direct upon the reedvalves, as shown in Fig. 8,0r through aspringr0 lever, b,as shown in Figs. 12 and 13, agreater number of reeds can be arranged in the music-box, and the same can be made considerably smaller than by the present arrangement of levers for operating the reed-valves.

15 I do not broadly claim a musical instrument having a double rest for the music-sheets, as such a construction is described in Patent N 0. 298,066, granted to G. H. Chinnock, May 6, 1884; but

2:) I do claim- 1. The combination of ring R, adapted to carry perforated music-sheets N N, with the boxes B G, bellows L, and tubes connecting the bellows with said boxes, substantially as 25 specified.

2. The combination of toothed ring R with worm S, boxes '8 0, rod F, bellows L, and tubes E M, substantially as specified.

3. The combination of ring R, conical sheets N N, boxes B O, bellows L, tubes E M, and 3c flexible joint D, substantially as described.

4. The combination of ring R, with conical sheets N N, and box C,which contains rodsa,

for operating the reeds, said rods being placed at right angles to the sheet, substantially as 5 and for the purpose specified.

5. The combination of sheet N, supported by ring R, with box 0, rod a, guide-tubes h, levers b, and reed-valve 12, substantially as specified.

6. The combination of box 0 with rods a, having conical heads a, and elastic piece d, with levers b, reed-valve v, reed-plate g, and with spring 0, substantially as specified.

In testimony whereofl have signed my name 5 to this specification in the presence of two subscribing witnesses.
